TIME-STAMP.

- To all whom z't-may 0012 06m:

tickets or checks, report slips, etc., by ship-' ping and receivingclerks, watchmen and others for stamping reports, etc., and in short bywidely varied classes of persons for widely varied purposes.

In the accompanying drawings, which illustrate one embodiment of theinvention, Figure l is a plan View of the time stamp; Fig. 2 is a viewof one side of the time stamp, part of the upper jaw being broken away;Fig. 3 is a central longitudinal section on line 33 of Fig. 1; Fig. 4 isa view of the side opposite to that shown in Fig. 2; Fig. 5 is a planview of the face of the upper jaw; Fig. 6 is a plan view of the face ofthe lower jaw; Fig. 7 is a cross section on line' 77 of Fig. 6; Fig. 8is a cross section on line 88 of Fig. 1; and Fig. 9 is a detail View inplan of the parts connecting the clock works and the type hands.

Referring to the drawings, A and B represent respectively the lower andupper members of a pair of parallel-movement jaws. These jaws areprovided as usual with rearwardly extending arms a and b, slotted attheir ends as shown at a and b. In order to secure the accurateregistering of the two jaws when they are brought together, a socket andtenon are provided between the opposed faces of the arms a and b, thesocket being shown at a and the tenon at 6 This socket and tenon areslightly tapered in form as shown. Said parallelmovement jaws aresecured to and operated by a pair of pivoted pincer-handles C and D ofusual construction, said handles each being forked as shown at 0 and d,and pivoted to each other at f. The forks c and (Z are pivotedrespectively to the arms 6 and a of the jaws at 0 and d, and bars 0 and(Z Specification of Letters Patent.

connecting the forks o and d respectively work in slot-s a and b. Thepincerhandles and consequently the jaws are normally held open by aspring S, which is held at its ends between the handles D and G by thebosses or studs d and 0 One of said jaws, preferably the lower jaw A ismade hollow to provide a chamber a and carries a time piece comprisingclock works and type hands and dial stamping types. An annular disk 6 isscrewed into the opening of the chamber a and is provided with embossedor raised dial stamping types 0, as best shown in Fig. 6; the annulus eis locked in place by the set screw 6 Concentric with the dial stampingtypes 6, and rotatably mounted in the annulus e is a disk 6 providedwith a type hand 6 at the margin. On the center of the exposed surfaceof the disk 6 is a pad 6 for cooperating with movable date types carriedby the other jaw as presently to be described. A ring 6, screwed to theunderside of the disk 6 and provided with a flange 6 projecting underflange e on annulus 6, prevents the removal or dislodgment of the disk 6from its jaw.

Secured to the underside of the annulus e is a time piece or clock works9 which may be of any suitable construction, for operating the disk 6and type hands 6*. The chamber a containing the clock works 9 isprovided with an aperture a"=, through which a key or other instrumentmay be inserted for winding and setting the time piece. The aperture ais surrounded by a hub a covered by a cap a, which is provided with anarm a for locking the cap in place as hereinafter described.

Instead of operating the disk 6 and type hands 6 directly from the arborg of the time piece, which might result in stopping the clock should thejaws be held closed more than momentarily, the arbor g is connectedindirectly with the disk 6 with provision for lost motion between them,so that if the type hand is arrested and held stationary by the closingof the jaws, the action of the clock will not be affected for severalminutes-much longer than the jaws are likely to be kept closed. Themechanism for accomplishing this, consists of the cup 9 centrally fixedto arbor g, and turn ing therewith. The rim of the cup is provided witha slot 9 into which extends a pin g fixed to the underside of disk 6 Theslot 9 is broad enough to provide a clearance allowing considerable playof the pin 9 in slot 9 (See Fig. 9). The rim of the cup is also slottedat g to hold one hooked end of spring g within the hollow of the cup,the other hooked end of the spring engaging pin 9 The cup 9 beingrotated clock-wise by the time piece, carries the disk 6 and type hand 6in the same direction, the disk 6 being actuated by the spring g whichis stiff enough normally to hold the pin 9 against the side of the slotin the position shown in Fig. 9. Should the disk and the type hand bearrested by the closing of the jaws together, the rotation of the cup 9will not be affected until it has moved far enough to bring the pin 9into engagement with the opposite side of slot 9 the spring g beingmeanwhile compressed, which will consume several minutes. Upon againopening the jaws, the type hand 6 will be released and the spring 9 willrestore the disk and type hand, by means of pin 9 to normal positionwith relation to the cup 9 Referring now to the upper aw B and itsassociated parts; the face of the aw is provided with a central,circular aperture with which pad 0 of jaw A registers. Adjacent to thisaperture is the marginal pad h which registers with the path of the typehand 6 and surrounding pad h are the dial stamping dies h complementalto the dial stamping types 6 on jaw A. Mounted in a chamber in jaw B andprojecting slightly below the face of the jaw through the centralaperture, so as to engage the pad 0 are the movable type wheels 2',rotatably mounted on shaft 7' and bearing date stamping types, as bestshown in Fig. 5. On the upper side of jaw B is a hood K, pivoted to theforward end of the jaw at 70, and provided at its rear end with a tailpiece 72 turned downward and having a perforation through which pivotpin 0 passes. The pivot pin 0, which is removable, serves not only as apivot for the pincer C but as a bolt for securing the hood K in closedposition. One end of the pin 0 is provided with a nut Z, the nut and pinboth being bored to receive the loop of a wire Z, the pin ends of whichare sealed in any suitable way, as by a lead seal Z Thus the hood K whenclosed and sealed cannot be opened without breaking the seal Z The innersurface of the hood K is provided with a projection 70 which entersbetween the movable types 6 securely locking them in the desiredposition when the hood is closed, and preventing the user from alteringthe date. Then the hood K is closed its rim also covers arm a of cap athus locking cap a in place and preventing any tampering with the timepiece through aperture a A suflicient clearance is provided within therim of hood K to permit arm a to slide therein when the aws are closed.The upper aw also carries a counter M of usual construction, inclosedwithin the hood K. The counter is read through a glass covered aperture7s in the hood. The counter is operated each time the jaws are closed,by v means of a rod m which extends downward and is actuated by jaw A.(See Fig. 2). A bell N is secured within the chamber a of the lower jaw,which is sounded by a hammer n, actuated each time the punch is operatedby the plunger rod 91, extending upward into the path of jaw B.

A rotatable type piece R is mounted in the margin of jaw B at the side,bearing on one side the character A and on the opposite side thecharacter P, to indicate respectively A. M. and P. M. A spring 7 bearsagainst the upper side of the type piece R and yieldingly holds itagainst accidental rotation. It may be turned when desired by the slotT. On the opposite jaw A a complemental pad r is provided registeringwith the type piece R. Each tool is also provided with an identifyingnumber in type adjacent to the dial, as shown at T, which is impressedon the ticket or check beside the dial, thus indicating on each ticketwhat instrument was used and consequently by what conductor the ticketwas issued.

Near the margins of the front ends of the jaws are a punch P and itscomplemental die P. The punch P is made sufficiently long so that itwill enter the die P and perforate the paper before the stamp makes anyimpression. Thus when the jaws are operated, the first part of themovement will punch the paper and further or complete movement of thejaws will impress the time stamp on the paper. It will be seen thereforethat the punch may be used if desired independently of the stampingdevices; and further that as the punch ing precedes the stamping, thepunch will be certain completely to perforate the paper when the twooperations are performed successively, whereas if the punch and stampoperated at the same instant the stamp might arrest the jaws before thepaper had been completely perforated.
